Unidad Turística Embalse, Tourist complex in Calamuchita Department, Argentina.

Unidad Turística Embalse is a vacation complex with seven hotels and fifty-one bungalows positioned along the shore of Lake Ministro Pistarini in Argentina's Córdoba mountains. The accommodation options range across different categories, while the grounds include a swimming pool, medical services, and shops for guests.

The Ministry of Tourism built this complex between 1946 and 1951 during Juan Domingo Perón's presidency. The project was part of a broader plan to modernize Argentina by creating new public facilities for its citizens.

The hotels are named after native trees: Los Pinos, Las Acacias, El Piquillín, El Tala, El Espinillo, El Chañar and El Quebracho. Stays followed a fixed pattern of six nights and seven days, with waiter-served meals, welcome and farewell parties, cinema, games and dances, and guided walks. Hotel No. 5, the most luxurious, had parquet floors and marble stairs.

Provincial Route 61 crosses the grounds, so the complex is reached by road from Embalse city. The water tank doubles as a lookout point over the reservoir. As of 2017 only hotels 2, 4 and 7 were open; the other four stood abandoned, so check which buildings receive guests before arriving.

Hotel No. 5, El Espinillo, was the most luxurious of the seven, with parquet floors and marble staircases. In 1980 tourism authorities under the last dictatorship stripped these out and loaded them onto 15 trucks bound for Chaco; the trucks never arrived. Silver and alpaca tableware was also taken.
